  <div>
   <p>当需要对已备份的虚拟机指定磁盘恢复时，可以参考本节恢复虚拟机的磁盘至原虚拟机或新虚拟机。</p>
   <div class="section">
    <h4 class="sectiontitle">背景信息</h4>
    <p><span>本产品</span>支持使用备份副本、复制副本（不支持恢复至原虚拟机）、即时挂载产生的副本（副本需要已从虚拟机卸载）、导入的副本进行磁盘恢复，支持恢复至原虚拟机或新虚拟机。</p>
    <ul>
     <li>恢复磁盘至原虚拟机<p>恢复磁盘至原虚拟机时，如果原虚拟机对应槽位存在磁盘，该磁盘会被替换，如果对应槽位原磁盘还存在，则会尝试增量恢复（只有基于最新的备份副本，执行第一次恢复时才是增量恢复，其他恢复均为全量恢复。）；如果原虚拟机对应槽位没有磁盘，则会进行全量恢复，即创建磁盘进行恢复，并挂载在对应槽位上。</p></li>
     <li>恢复磁盘至新虚拟机<p>恢复磁盘到新虚拟机时，如果指定的新虚拟机对应槽位存在磁盘，该磁盘会被替换；如果新虚拟机对应槽位没有磁盘，则会进行全量恢复，即创建磁盘进行恢复，并挂载在对应槽位上。</p></li>
